Improved boot-crimp



UNTTED STATES PATENT EETcEO NATHAN DAY, OF ITHACA, OHIO.

IMPROVED BOOT-CRINIP.

Specification forming part of Letters Patent No. 52,394, dated February 6,1866.

To all whom it may concern:

Be it known that I, NATHAN DAY, of Ithaca,y

Darke county, Ollio, have invented a new and useful Boot-Crimp, and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specilication.

This invention relates to a new and improved device for forming the uppers of boots of that class in which a jointed crimping-board is adapted to be used in combination with a similarly-jointed clamp.

Figure l is a perspective view of a crimp embodying' my improvements. Fig. 2 is a side elevation, showing` the two members ot' the criml'iing-board and the stretcher detached.

A is a horse, composed ot' a slanting board resting at one end upon the ground and supported at its other end by two legs.

Io the horse A I iirmly attach the two members B B' ot' my clamp B O B' C'. To the xed members B B' are hinged the members O C.

D and E constitute, respectively, the foot and leg ot' my cri mping-board, said foot and leg being hinged together at F.

The clamp land crimping-board are peri'orated at b, c, d, and e, to receive pins Gr G', which, being inserted, compel the board and clamp to move in unison. The perforations d and c are made oblong in order to permit these movements.

H is a treadle, hinged to the Linder side ot' the horse A, and provided with a loop, l', which, being' engaged over the members O, C', and E ottthe clamp and board, collectively, enable them to be folded down in the operation of crimping.

The central plate or leaf, f, ofthe hinge F is indented at j" to receive the point of my visescrew J, which screw is provided with the customary ni pper-j aws K L and a bridge, M,whose points m m' are introduced under lips N N',

which project from the back edges of the foot and leg, respectively.

l) is a screw, by which the parts B C and B' C' are made to approach or recede from each other.

' The parts J, K, L, and M, I style, collectivel y, the stretcher.

Operation: The crimping board being' brought to its straight position, an upper being tacked over its front edge and made fast in the vise K L in the usual manner, and the clamp being` also brought to its straight or extended position, the board D E is then placed in the clamp and secured there by the insertion ot' the pins G G', and the parts B C and B' C' ot' the clamp are made to snugly compress the upper against the board by means ofthe screw O. The loop I is now thrown over the clamp and board, and the operators foot being applied to the treadle H the clamp and Aboard are deflected downward, as seen in Fig.

l, the vise being relaxed at the same time, it' necessary, in the usual way. i

The crimp being sufficiently deflected, the ends of the bridge M are inserted under the lips N N', and the screw O being relaxed, the board, with its upper smoothly and completely crimped, may be removed from 'the clamp and hung up to dry. l

I claim herein as new and of myinvention- 1. The arran gement of thejointed and lipped crilnping-board D E N N' and stretcher J K L M, for the purpose set forth.

2. The described combination ot horse A, jointed clamp B U B' C', jointed crimpingboard D E, loop I, treadle H, and pin G, for the purpose explained.

In testimony ot' which invention I hereunto set my hand.

NATHAN DAY.
